FAULT TOLERANT CONTROL FOR UNCERTAIN SYSTEMS WITH PARAMETRIC FAULTS

A fault tolerant control (FTC) architecture based on active fault diagnosis (AFD) and the YJBK (Youla, Jarb, Bongiorno and Kucera) parameterization is applied in this paper. Based on the FTC architecture, fault tolerant control of uncertain systems with slowly varying parametric faults is investigated. Conditions are given for closed-loop stability in case of false alarms or missing fault detection/isolation.
